Why Is My Trane Thermostat Touch Screen Not Working?

Several reasons can cause your Trane thermostat display screen to stop working. But below are some of the possible reasons:

a. Battery Issues

More times than not, battery issues are usually the reason your thermostat display screen will stop working. Most Trane thermostats are battery-powered. So if there’s an issue with the battery, it will affect the display screen.

For instance, it could be that the battery is low. If this is the issue, you will see a low battery signal on the display screen. Also, it could be that the battery is damaged. If you’ve used the battery for more than 12 months, this may likely be the issue.

b. Dust & Dirt

If the environment where the Trane thermostat is installed is dirty, it can result in the accumulation of dirt on the display screen. Over time, the dust can get in and damage the screen.

One way to prevent this is to make sure the room is always swept and cleaned from time to time.

c. General Power Issue

A general power issue can affect the touch screen on your thermostat. For instance, if the circuit breaker in your home trips off, it can affect thermostat functionality. The same applies if you have a blown fuse.

d. Locked Screen

If you notice that your screen display is still functional but you can’t change the settings on the screen, it means the screen is locked. The two options available to fix this are to either unlock the screen or reset the thermostat.

e. Minor Glitch

A minor glitch on the device can cause the display screen to malfunction. For instance, if your device is running on an outdated firmware version, it can affect the display functionality.

The first step is to check the display screen for dirt and dust. If the display screen is dirty, use canned air to gently remove the dirt from the screen. Buy a Quality Canned Here On Amazon. Most times, cleaning the display screen can get it working again.

b. Switch Batteries

If you’ve used the batteries in your device for up to 12 months, it’s time to change the batteries. Also, if you changed the batteries recently, it could be that the new battery pair is not compatible with your device.

First, check for and replace a blown fuse with a new fuse. Also, check the circuit breaker and reset the circuit breaker if there is a need for it. Finally, check for wiring installed during the installation process for any issues.

Remember to turn off your device before you start checking for any power or an electrical issue. It’s best to get an HVAC technician to check for these issues.
